Abstract

In order to determine the best weed control method in dry-farming of rapeseed and reach to optimal yield and also the best use of soil-water sources in drylands, this experiment was conducted in three years as RCBD desing in three replications at Maragheh, Dry Land Agricultural Research Station on Oilseed rape Cv. PF7045,91. The factors of trial were A1: No weed control (check), A2: One hand weeding before stem elongation, A3: Two hand weedings (one in mid of rosette and other before stem elongation), A4: Mechanical control with sweep before stem elongation, A5: Chemical control with Treflan 1.5 litha-1 before planting and A6: Chemical control with Treflon 2.5 litha-1 before planting. Combined analysis of the data showed that year effect was significant at 1%propability level on weeds per unit area, pods per plant, seeds per pod, grain yield, oil percentage and percentage of moisture lost. Only seed per pod and 1000 seed weight were affected by yearx control methods interaction. Two hand weeding streatment with 487.5 kgha-1 grain yield was arranged in class A, and chemical control by Treflan 2.5 litha-1 with 285 kgha-1 grain yield in class B. Chemical control by 2.5 litha-1 Treflan with 107 kgha-1 oil yield, arranged after two hand weeding, treatment. Over-all chemical weed control treatment by 2.5 litha-1 Treflan before planting is recommended for Maragheh region and other regions with similar climatic conditions.
